Hi, I've a unique requirement where the transaction number should be automatically generated (increment). I can't use AUTO_INCREMENT column. The TRAN_NO is supposed to be in "YYYYMFFFFF" format, where:
Field: TRAN_NO CHAR(10) M = Encoded current month (A: January, B: February, C: March . L: December) YYYY = Current year (e.g. 2004, 2005, ...) FFFFF = Running serial number in hexadecimal format (so the smallest number is 00001 and the largest number would be FFFFF; the serial number will reset to 1 at the beginning of each month) How can I generate this number using MySQL without running into concurrency problem? Also, this is a web-based app and I am planning to use PHP for coding. My production environment is MySQL 4.0.17 on Linux. Development platform is Windows XP with MySQL 4.0.17. TIA.
